Environmentally friendly trivalent chromium is now a proven, economical alternative to hexavalent chromium coatings, offering high corrosion resistance for CWM Al, Mg and Zn die castings in a range of applications.

With a bright, cosmetically pleasing finish, this alternative combined conversion-functional coating meets stricter commercial and U.S. and European Union environmental mandates, avoiding the concerns with prohibited products using toxic hexavalent chromates.

Results of tests to ASTM standards demonstrate salt-spray protection up to 168 hours on Aluminum alloy 380.
